Does a boat need a keel?

The keel is often a structural beam that runs in the middle of the boat from bow to stern. The purpose of the keel is to help give the boat greater stability and control while moving forward. Without the keel, a boat might slip or skim on the water which is often common in vessels with an entirely flat bottom.

Keel repair may become necessary from many sources of damage such as groundings, keel bolt corrosion, actual lead keel corrosion problems on the surface and internally within the casting. Any of these scenarios can be a safety factor and a possible structural issue that must be addressed as soon as possible.
